The area of a circle is pi * radius squared, thus the area of the circle is 64(pi). Since we have a sector with 90 degree angle, the area of the sector is exactly 1/4 the area of the entire circle, or 16(pi)
Answer: y=1/9x-8
Explanation: m= (y2-y1)/(x2-x1)
(-9 - -8) / (-9 - 0) = -1 / -9 = 1/9
1/9x is the slope
B = -8 since it’s x value is 0
So in y=Mx+b form the solution is
Y=1/9x-8
G'Day mate! Here's the answer:
53 1/3
1. 6(3 + 6) - 4/5
2. 6 x 3 is 18, and 6 x 8 is 48
3. 18 plus 48 is 66
4. 66 - 4/5 = 266/5
5. 266/5 as mixed number is 53 1/5
Answer:
In Table (b)

Step-by-step explanation:
By definition, Inverse proportion equations have he following form:

Where "k" is the Constant of proportionality.
Solving for "k":
Having the values of "x" and "y" given in each table, you can check if the products of "x" and "y" is equal to a constant value.
Then:
(a) For
:

For
:

For
:

For
:

Since the product of the values of "x" and "y" is not constant, they are not inversely proportional.
(b) For
:

For
:

For
:

For
:

Notice that the Constant of proportionality is:

Therefore "x" and "y" are inversely proportional.
